' RADIOIPHONE METER.

original application filed September 8, 1922, Serial No. 588,842. Divided and this application filed August 18, 1924. Berial No. 732,797.

Our invention relates to radiophone systems, and has for its object the combination of such a stem with an electric light, power, or ralway system, se that.the WireS of said systemmay be employed for metering. This application is a ivis1on of our pr1or co end1ng application, Serra] No. 586,842, ed September 8, 1922.

In the present case, we attam our object by locating a standard type of radiophone receiving instrument at consumers stations on. an electric light, power, telegraph or railway system, and broadcast from a central station, which may be the central power station or a substatioh belonging to the systcm. At the radiophone stations, we provide switching connections from the instruments to the current mains, and through these connections efiect current feed to the filament and plate Circuits and for metering. The Central station 1s provided with amplifying and modulatmg apparatus for original matter, and withrelaymg apparatus for distr1butmg to the subscribers 01 local consumers programmes and other matters receivcd from a distance. By thus organizing the system so that tire subscribers are dependent solely on 'the r iocal central station for all radio communication, it is possible to unify the serwcegn all respects, and to make metered service charges on a fait and accurate bas1s.

It is to be understood that the pr1nc1 les herein set forth are not limited as ta}: e1r embodiment to lighting, power or raflway circuits as such, but that any conduictor or wire circuit capable of carrying and supp 1ying the necessary current an performm the fonctions describcd herein, may be use in the present invention, and the related 1nventions hereinbefore referred to. Among such conductors are telegraph fines, trolley wires, feed wites' and sable et lighting, power and railwa systems, third rails and underground trol ey conductors, and fonce and tree wires used by ranchers, lumber interests and others in sparsely setthd districts.

Our invention is illustrated in the accompan in drawing, in whih:

'1 cigare is a typical diagram showing a radiop one station and the connections t0 a central power station.

Referring to the drawing we have therein shown a portion of a system of power and communication circuits, one radiophone RR, and the general arrangement cf arad1o for the mater RM is supplied through this circuit, The metcr may be of any standard type adapted to the current employed. In

the present case alternating current at cycles, single phase, is prsupposed.

The receivmg instrument RR is equipped with antenna 25, coupler 28, etc., as usual. On the audio side, transformer 14 supplies the armature of the loud speaking receiver 56, its field being fed direct from wires 17-18.

In operation, a subscriber desiring radio service, plugs his set in on the line M through means of the plug P, which supplies power to his receiving set RR through conductors 1718 and to the meter 22 through branch wires 19-20. The meter therefor startS into operation and continues to record the length of time the connection is maintained. The receiver RR, being supl1ed with power Will 110W pick up, the roadcast signaling to, which it is tuned through the antenna circuit 2528 and translate it into amplified audible signals through the transformer 14 and loud speake1 56 in a manner which will be understood by those skilled in the art. In"the present instance the,receiver RR is tuned to.the transw mitting station RT so that broa cast matter is receivcd therefrom.

We claim:

1. In a system of the class described, a central power distributing station and a current supply circuit extending from said power station to consumer stations, a consumer station connected with said su ply circuit, permanently connected outlets iiom said circuit in said consumer station, power translating devices adapted to be connected through said outlets to said supply circuit, 21 rad1o receiving set at said consumer station having an energizingircuit, a time use meter, and a meter motor With a driving circuit therefor, switch terminals connected to both said energizing circuit and to said mater motor circuit, forming a single inseparable terminal unit adapted to be connected to and disconnected from said outlet terminals at will, whereby the radio receiving set iSnormally entirely disconnected from said power supply circuit, and cannot be connected thereto for power supply for its operation without also connecting and operating its meter motor torecord its time use.

2. In a system of the class described, a central power distributing station and a current supply circuit extending from said power station to consumer stations. a consumer station connected with said supply circuit, permanently connected outlets from said circuit in said consumer station, power translating devices adapted to be connected through said outlets to said supply circuit,

21 radio receiving set at said consumer statien havin an encrgizing circuit, a time use meter, and a meter motor with a driving circuit therefor, a pair of switch terminals connected to both said energizing circuit and to said meter motor circuit, in parallel, forming a single inseparable terminal unit adapted to be connected to and disconnectcd from said outlet terminals at will, whereby the radio receiving set is no'rmally entirely disconnected from said power supply circuit, and cannot be connected thereto for power supply for its operation without also connecting and operating its meter motor t0 record its time use, and whereby also the power consumption of the meter niotor is independent of the power supplied to energize the radio receiving elements, and variations in either will not affect the other, said motor being adjusted for constant speed.

In testimony whereof we hereunto afiix our signatures.
